The BOSTON GEAR 18806 is a steel thrust bearing washer designed to manage axial loads in rotating shaft assemblies. With a 3/16 inch bore, 3/8 inch outside diameter, and 3/32 inch thickness, this compact washer-style bearing fits into tight spaces where axial load separation is required between mating components. It is commonly installed by mechanical technicians and millwrights working on motors, gearboxes, pumps, and similar rotating equipment. The all-steel construction provides durability in industrial and light commercial applications where reliable thrust load management is essential.
This thrust bearing washer suits residential and light commercial mechanical assemblies where shaft-end float must be controlled or axial loads must be isolated between components. It is appropriate for use in small motor applications, fan assemblies, pump shafts, and gear drive systems requiring a low-profile thrust element. Its compact dimensions make it a practical replacement or service part for standard fractional-inch shaft configurations.
Designed as an OEM-style replacement thrust bearing washer for rotating shaft assemblies using 3/16 inch fractional bore sizing in industrial and commercial mechanical equipment.
Installation is typically performed by a qualified millwright or mechanical technician. Always de-energize and lock out the equipment before servicing any rotating components. Ensure the shaft is clean and free of burrs before seating the washer to prevent misalignment or premature wear. Follow applicable ASME or equipment manufacturer guidelines for assembly tolerances when stacking thrust elements.
